May Night and Morning, hymned with lauds, united, fair to look upon, Strong Mothers of the sacrifice, seat them together on the grass.

The traditional hymn heading, not a statement inside the verse.

Insufficient evidence

No other passage in this corpus carries this wording. That is a statement about the four collections held here, not about the Vedas.

How attribution was recorded1

PER_PASSAGE is an attribution the source states verse by verse; CONTAINER_INHERITED is a containing hymn's label projected onto each of its mantras. The two must not be summed: 15,177 of the 17,889 seer edges are inherited, every one of the Atharvaveda's 5,084 is, and every one of the Yajurveda's 2,240 is source-stated, so a blended total compares a statement of the text against a projection of this build.
